The Raven Coloured Progressive Matrices were administered on group or individual bases to children ranging in age from 4 yr. 9 mo. to 11 yr. 0 mo. (N = 728). Factor analysis yielded three factors: 1. Perceptual closure involving complex figures and patterns with heterogeneous inner structures, 2. Concrete and abstract reasoning, 3. Completion of homogeneous patterns and recognition of given elements. Factor matrix comparisons across age groups resulted in a mean similarity coefficient of .75. Comparisons of data with earlier analyses also resulted in high similarity. This supports the hypothesis of a three-factor structure rather than a four-factor solution or a simple dual classification into items which can be solved by perceptual processes and those which require conceptual solutions.
Although disputed, most researchers in the field of suicide and mass media agree that the studies carried out to date have substantiated the existence, under certain circumstances, of genuine suicidal ‘contagion’ from suicide reports in the media. The fact that many studies have demonstrated an association between media reporting of suicide and actual suicidal behaviour has also prompted the issue of various types of recommendations on how the media should report on the subject of suicide to avoid imitative behaviour. The purpose of this chapter is to discuss and identify the problems associated with research on suicide and the media, with a number of seminal articles published over the years serving as examples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
